The present invention relates to a system and a method for electricity management, and more particularly, to a system and a method for electricity management used to test an uninterruptible power supply apparatus.
2. Description of the Related Art
With the booming development of the information industry in recent years, a variety of hardware equipment, such as personal computers, communication equipment, and workstations, is broadly applied in all strata of society. As information itself is a high value-added product, people try every means to ensure the security of information and the normal operation of computer systems, so the requirement for a power supply with consistent quality has become stricter. While electronic power equipment has been heavily used, the derived harmonic waves may result in poor-quality electricity, and factors such as natural disasters, all make it impossible for electricity providers to guarantee a stable power supply with high quality. Thus, an uninterruptible power supply (UPS) becomes an indispensable device for computers or communication systems, and how to effectively test the function of the uninterruptible power supply system also becomes an important issue.
The common practice of testing the function of an uninterruptible power supply system is to discharge electricity with electronic load equipment (Loader) after removing part of the batteries in the system, and then installing them back into the system after the capacity of the other batteries has been measured and the removed batteries have been fully recharged. The reason that only part of the batteries is removed for testing is to avoid a blackout during the testing. Such a method results in shortcomings include: manpower to be allocated to battery disassembly/assembly, the expense of the discharge/recharge equipment required during the testing process builds up an increased cost structure, and moreover, an estimate of the available service time during the blackout calculated based on the discharging capacity discharged through a discharge machine may be inaccurate and unreliable. In addition, the electricity discharged during the testing conducted by the conventional testing method indicates a total waste of energy. Therefore, it is necessary to provide an electricity management system and electricity management method for testing a UPS system periodically and automatically so as to manage the status of the uninterruptible power supply system, furthermore, to control the risk of power blackout efficiently in an attempt to eliminate the shortcomings of the prior art.

What should be noted is that every aforementioned element not only can be disposed as a hardware apparatus, a software program, a firmware, or any such combination, but also can be disposed through a circuit loop or any appropriate type. Furthermore, every element can be disposed as an independent type as well as any combined type. The present embodiment exemplifies only a good embodiment of the present invention; not all possible combinations are described in detail. Nevertheless, those skilled in the art should understand that the aforementioned elements are not all necessary. In order to present an embodiment of the present invention, it is also possible to include other detailed elements of the prior art. Any element can be omitted or modified depending on requirements, and other elements may exist between any two elements.
According to one embodiment of the present invention, the electricity management system 1 allows a user to conduct a functionality testing of the uninterruptible power supply apparatus. The data management unit 10 is electrically connected with the cabinets 20 a, 20 b; when a user wants to conduct a testing, the data management unit 10 can configure a testing instruction and send the testing instruction to the cabinet 20 a or 20 b to begin the testing. The cabinets 20 a and 20 b are disposed with an electronic equipment 21 a and 21 b, respectively, which the electronic equipment 21 a and 21 b can be a hard disc, a server or a combination of both, but the present invention is not limited to this disposition.
According to one embodiment of the present invention, the control units 30 a and 30 b are electrically connected with the cabinets 20 a and 20 b, respectively, and the uninterruptible power supply apparatuses 40 a and 40 b are electrically connected with the control units 30 a and 30 b and with the cabinets 20 a and 20 b, respectively. By these connections, the control units 30 a and 30 b can measure a set of battery parameters of the uninterruptible power supply apparatuses 40 a and 40 b. The power switches 50 a and 50 b are electrically connected with the control units 30 a and 30 b respectively and with the external power supply 80. By these connections, the control units 30 a and 30 b can control the power switches 50 a and 50 b to shut down the external power supply 80, and the cabinets 20 a and 20 b can be powered by the uninterruptible power supply apparatuses 40 a and 40 b instead, thus to test the uninterruptible power supply apparatuses 40 a and 40 b.
Also to be noted is that the electricity management system 1 does not necessarily include only two sets of the cabinets 20 a and 20 b, the control units 30 a and 30 b, the uninterruptible power supply apparatuses 40 a and 40 b, and the power switches 50 a and 50 b. The number of the cabinets and other apparatuses can be increased or decreased depending on requirements.
Please refer to FIG. 2, which is a procedure flow chart illustrating the electricity management method according to one embodiment of the present invention. The electricity management method of the present invention is described below using the electricity management system 1 shown in FIG. 1. What should be noted is that the electricity management method of the present invention is not confined to the usage of the electricity management system 1 shown in FIG. 1.
First of all, the system proceeds with step S1: the data management unit configures and sends a testing instruction to a to-be-tested cabinet.
Please refer to FIG. 1, when the user intends to conduct a testing on the uninterruptible power supply apparatus, the data management unit 10 configures a testing instruction and sends the testing instruction to the corresponding cabinet first. Generally speaking, the data management unit 10 can arrange a testing schedule of every cabinet and conduct tests automatically according to the testing schedule. In the present embodiment, for example, when the user wants to test the uninterruptible power supply apparatus 40 a, the data management unit 10 sends the testing instruction to the corresponding cabinet 20 a of the uninterruptible power supply apparatus 40 a first.
According to one embodiment of the present invention, the testing instruction at least includes a service power to configure the service power used by the cabinet 20 a during the testing process. The testing instruction can also include a termination condition, wherein the termination condition can include a default voltage, a default time or a default value of power supplied of the uninterruptible power supply apparatus 40 a, such that when the operation voltage of the uninterruptible power supply apparatus 40 a is lower than the default voltage, the operation time of the uninterruptible power supply apparatus 40 a exceeds the default time, or the amount of power supplied by the uninterruptible power supply apparatus 40 a exceeds the default value for power supplied, the testing is stopped. However, what should be noted is that the termination condition is not confined to these aspects.
Next, the system proceeds with step S2: the control unit controls the power switch to shut down the external power supply, and the tested cabinet is powered by the uninterruptible power supply apparatus instead.
According to one embodiment of the present invention, after the data management unit 10 sends the testing instruction to the cabinet 20 a, the corresponding control unit 30 a controls the power switch 50 a to shut down the power supply from the external power supply 80 to the cabinet 20 a. At the same time, the cabinet 20 a is powered by the uninterruptible power supply apparatus 40 a instead so as to start the testing process. Also to be noted is that the power switch 50 a can be controlled by an independent element and not necessarily by the control unit 30 a.
Next, the system proceeds with step S3: the control unit measures a set of battery parameters of the uninterruptible power supply apparatus.
According to one embodiment of the present invention, when the uninterruptible power supply apparatus 40 a supplies power to the cabinet 20 a, the control unit 30 a continues measuring the uninterruptible power supply apparatus 40 a to obtain a set of battery parameters of the uninterruptible power supply apparatus 40 a. The set of battery parameters can include voltage data, electric current data and temperature data, but the present invention is not confined to this aspect. What should be noted is how the set of battery parameters of the uninterruptible power supply apparatus 40 a is obtained is familiar to persons having ordinary skill in the art of the present invention, which falls into the scope of the prior art; therefore, it is not described in detail herein.
Next, the system proceeds with step S4: according to the termination condition, the external power supply is turned on to power the tested cabinet instead of the uninterruptible power supply apparatus.
According to one embodiment of the present invention, during the testing process of the uninterruptible power supply apparatus 40 a, the control unit 30 a continues to determine whether the termination condition is met. When the termination condition is met, the control unit 30 a controls the power switch 50 a to turn on the external power supply 80 to power the cabinet 20 a instead of the uninterruptible power supply apparatus 40 a.
Next, the system proceeds with step S5: the control unit calculates the power capacity of the uninterruptible power supply apparatus according to the set of battery parameters and returns the power capacity to the data management unit.
According to one embodiment of the present invention, after the uninterruptible power supply apparatus 40 a stops supplying power to the cabinet 20 a, the control unit 30 a calculates the power capacity of the uninterruptible power supply apparatus 40 a according to the measured battery parameters, and then returns the power capacity to the data management unit 10. What should be noted is that how the power capacity is calculated based on the battery parameters should be familiar to persons having ordinary skill in the art of the present invention, which falls into the scope of the prior art. Therefore, it is not described in detail herein.
Next, the system proceeds with step S6: the data management unit determines whether the power capacity is less than the default capacity.
According to one embodiment of the present invention, the data management unit 10 then determines whether the power capacity of the uninterruptible power supply apparatus 40 a is less than a default capacity. If the power capacity is less than the default capacity, then the system proceeds with step S7; otherwise, the whole testing process is terminated.
Finally, the system proceeds with step S7: the data management unit configures a service power during a blackout for the tested cabinet.
During step S6, if the data management unit 10 determines that the power capacity of the uninterruptible power supply apparatus 40 a is less than the default capacity, then the data management unit 10 configures a service power during a blackout for the cabinet 20 a. The service power during a blackout can prevent the uninterruptible power supply apparatus 40 a from supplying a greater amount of power to the cabinet 20 a during a blackout, by doing so the power supply time of the uninterruptible power supply apparatus 40 a can be extended to conform to the target time of the power supply.
What should be noted here is that the electricity management method of the present invention is not confined to the order of the aforementioned steps. The order of the aforementioned steps can also be changed as long as it achieves the objects of the present invention.
To sum up, the present invention has characteristics that are different from the prior art in terms of the objects, means, and function, and the present invention thus merits a patent. What should be noted is that the aforementioned embodiments are provided for illustration only, and not for the purpose of limiting the scope of the invention as defined by the appended claims.
